Including a number of fields to rows in Tableau is a helpful method that lets you show further information dimensions in your visualizations. By putting a number of fields on the Rows shelf, you’ll be able to create a hierarchical or faceted view of your information, making it simpler to research and perceive.
So as to add a number of fields to rows in Tableau, merely drag and drop the specified fields from the Fields pane onto the Rows shelf. You may add as many fields as you want, and the order wherein you add them will decide the hierarchy of your visualization.
